The Hayward HCF Series 700 Sq Ft Cartridge Filter is a heavy-duty commercial cartridge filter system designed to save thousands of gallons of carefully balanced, heated pool water per month through elimination of backwashing. The Dual Quad-Cluster design houses eight compact cartridges totaling 700 sq ft of high-performance filter media — delivering extra-long filter cycles and heavy-duty dirt-holding capacity for aquatic facilities.
Built with Noryl™ bulkhead fittings for strength and heat resistance, 2 in × 2-1/2 in connections with full 2-inch internal piping, combination pressure and filter cleaning cycle indicator gauge, full-size 1-1/2 inch integral drain, and heavy-duty tamper-proof clamp. NSF/ANSI Standard 50 certified. Backed by a 3-year warranty with 1-year labor.
Key Features
700 Sq Ft Dual Quad-Cluster Design
Eight compact cartridges in two quad-cluster groups — 700 sq ft of high-performance filter media for maximum commercial dirt-holding capacity.
No Backwashing — Saves Thousands of Gallons
Eliminates backwashing entirely — saving thousands of gallons of heated, chemically balanced pool water per month vs. sand or D.E. filters.
Eight Compact Cartridges — Easy Cleaning
Eight smaller cartridges are easier to handle and rinse than fewer large elements — fast, manageable cleaning cycles.
Noryl™ Bulkhead Fittings
Noryl thermoplastic provides extra strength and heat resistance for long-term commercial service.
Combination Pressure/Cleaning Cycle Gauge
Integrated indicator gauge shows both filter pressure and when the cleaning cycle is due — no separate tracking needed.
2" × 2-1/2" Connections
2 in and 2-1/2 in connection options with full 2-inch internal piping for commercial high-flow compatibility.
Full-Size 1-1/2" Integral Drain
Fast and complete tank flushing for maintenance and winterization.
Heavy-Duty Tamper-Proof Clamp
Securely fastens tank top and bottom — quick access to all eight cartridges when cleaning is needed.
NSF/ANSI Standard 50 Certified
3-year warranty on equipment, 1-year labor warranty.
Who It's For
- Commercial aquatic facilities — hotels, fitness centers, community pools — where water savings and reduced chemical loss from backwashing matter
- Facilities that want the finest cartridge filtration with 700 sq ft of capacity in a single unit
- Operations where heated pool water conservation is important and backwash waste is unacceptable
- Commercial installations requiring NSF/ANSI 50 certified filtration with a 3-year warranty

Frequently Asked Questions
How much water does eliminating backwashing actually save?
Commercial sand or D.E. filters typically use 200–400 gallons per backwash cycle, often performed weekly or more frequently. At one backwash per week, that's 10,000–20,000+ gallons per year of heated, chemically balanced pool water discharged to drain. A cartridge filter like the HCF7030C eliminates this waste entirely — particularly significant for heated indoor pools where the cost of conditioning replacement water is high.
Why use eight smaller cartridges instead of fewer large ones?
The Dual Quad-Cluster design with eight compact cartridges allows staff to clean one or two cartridges at a time rather than handling very large, heavy elements. Each cartridge is a manageable size and weight for a single person to remove, rinse, and reinstall, reducing labor time and physical strain during routine maintenance.
What is Noryl and why does it matter for commercial applications?
Noryl is a high-performance engineering thermoplastic known for excellent dimensional stability at elevated temperatures and resistance to pool chemicals. In a commercial environment where pool water temperature and chemical concentrations can be higher than residential pools, Noryl bulkhead fittings provide more reliable long-term performance than standard PVC or ABS fittings.
